Container



Patented July 6, 1937 condamne.

Application July 19, 1934, Serial No. 136,070 '1 Claims.' (Cl. 22d-5.5)

My invention relates to new and useful improvements in containers and more particularly to a container formed of peper and adapted for holding liquids such las milk although it will be understood that the same might equallyes well be used for holding other liquids, granules or the like.

The principal object of the invention resides in the provision of a novel form of closure adapted to be placed in position after the container has been lled and secured to prevent -accidental displacement or leakage of the contents.

Another object of the invention consists in the provision of a novel formof closure adapted to be positioned Within the end of the container and initially held by engagement of a portion oi the body therewith and then sealed by the use of an adhesive or sealing material received in a recess formed in the closure.

Still another object of the invention resides in the provision of a novel form of closure adapted to be inserted in the end of the container, the closure being formed with an edge ange adapted to be engaged by an lnturn'ed portion of the body oi the container, the closure being 'further provided with a recess to receive an adhesive or sealing material which, when hardened, securely holds and locks the inturned end of the container into tight sealing engagement with one face of the ange of the closure while at the same time holding the opposite face of the flange of the closure in tight engagement with the inner wall o the body.

With the above and other objects in view, which will appear as the description proceeds, my invention consists in the novel details of construction, and arrangement of parts, described in the following specification and illustrated in ther accompanying drawing, and while I have illus trated and described the preferred embodiments of the invention, as they now appear to me, it will be understood that such changes may be made as will fall within the scope of the appended claims.

In the drawing:-

Fig. 1 is a top plan.

Fig. 2 is a side elevation with parts broken away. A

Fig. 3 is a fragmented detail showing a body of the container with'a closure in position ready for insertion into the end of the container.

Fig. 4 is a. view similar to Fig. 3 with a closure inserted in the body of the container.

Fig. 5 is a. view similar to Figs.' 3 and 4 with the end of the body of the container folded into interlocking engagement with a closure; and

Fig. 6 is a fragments! detail showing the sealing element or material for holding and securing A the closure into the body of the container.

In the drawing I indicates the body portion of the container which is cylindrical in form and tapered, as shown more particularly in Fig. 2 `of the drawing, to' be of greater diameter at the normal bottom than at the normal top,y the body being formed of paper folded into the shape shown with the edge portions overlapped and sealed to provide the longitudinal seam indicated at 2. The smaller end of the body i will be closed by the disc 3 which has the inwardly directed flange it, the flange being secured to the inner wall of the body i by suitable adhesive and the end of the bodybeing curled or folded inwardly to engage the outer face of the disc 3, as shown at 5 in Fig. 2 of the drawing.

Normally the opposite end of the container or body will be left open for lling purposes and when filling the container will be inverted and supported by its smaller end portion closed by `the disc 3. When filled with the desired material the closure disc d will be inserted into the end of the body as shown in Fig. d of the drawing. This closurel disc d is preferably of central concavo-convex shape with the convened face extending' inwardly of the body of the container this concave-convex portionbeing indicated at l'. Extending around the concave-convex portion is the relatively at portion d with its edge bent to form the inclined flange 9, the edge of which in turn is bent to provide a vertical flange i@ with a groove or recess ii between the inclined Harige S3 and the vertical Bange. When inserted into the end of the body i, as shown more particularly in Fig. 4 of the drawing the outer face of the ange lil will tightly engage the inner surface of the body i, this tight engagement'being accomplished by pressing the closure into the tapered body. After the closure 6 has been positioned. as shown more particularly in Fig. 4 of the drawing, the end of the body i will be folded inwardly, as shownV at l2, to extend over the end of the vertical flange iii and to engage the Ainner surface thereof. By reference to Figs. 3 and 4 of the drawing it will be seen that the vertical ange i@ is of somewhat less height than the flange 9 so that when the end of the body l is turned inwardly, as shown at i2, the end'oi the body will be onthe same planeas the straight portions 8 of the closure disc.

After the end of the body has been .turned inwardly. as shown at '|2, then high temperature liquid adhesive and sealing material, indicated at i3, is placed into the recess Il and permitted to harden. When it hardens itacts to hold and lock the inturned end I2 into tight sealing engage ment with the inner face of the ange I0 and at the same time holds the outer face of the ange lo into tight sealing engagement with the inner surface of the body l. hardened then the container may be inverted to what may be termed its normal position with its After the material has for.

larger end lacting as a bottom therefor. Preferably the sealing material I3 is in the form of wax or similar material and forms what might be termed a lock. At times it might be desirable to use a wedge infthe form of a ring of wood, metal or possibly rubber, each of which would act in the same manner as ydoes the wax or similar material..

From the above detailed description it` is` thought that `the construction of the container and manner of use will be clearly understood. As has been stated, the closure disc 3 is initially secured in one end of the body I and when filling the container the same will. be positioned or invetted to be supported by that end closed by the disc 3. This permits the container to be filled through the open end and then the closure disc 6 will be positioned and sealed as described. When thus sealed the container may be again inverted to itsnormal position with the larger end acting as a bottom or support. The wedge formed by the material I3 acts as a lock and prevents the fiange I 0 of the closure 6 from breaking away from the wall of the body I and at the same time prevents the inturned portion I2, of the body, from breaking away from its engagement with the inner face of the flange I0. As shown more particularly in Fig. 6 of the drawing, a certain amount of the material I3 engages around the end of the inturned portion I2 and acts as a further seal or adhesive there- The straight portion 8, of the closure 6, being on the same plane as the end of the body after being turned inwardly, as shown at I2, will engage the support on which the container is held and thus act in supporting the closure 6 against the weight of the material in the container. I want to emphasize the fact that the hardened material I3 acts as a`v lock to prevent the disassociation of the co-related parts unless the wedge or locking material is actually broken apart.

Preferably the container will be coated or treated with paraffin or the like and as the material I3 will preferably be introduced at a high temperature it will melt the coating material originally placed on the wall or body of the containenwhich aids in forming a tight seal.
